Fluorescent Benzazole Dyes for Bloodstain Detection and Bloody Fingermark Enhancement

Abstract

Bloodstains are the most common and useful type of physical evidence in crime investigation. The detection and examination of bloodstains are of great value in the reconstruction of a crime scene and linking a criminal or the victim with the crime scene. There is a wide variety of chemicals available for detecting bloodstains and enhancing bloody fingermarks, however, they have several associated challenges. For instance, they are generally unsuitable for dark and multi-colored substrates.
